General :: Command Line - Use Find To Find Text Files?

Jul 15, 2011

Is there a way to specify to find that I only want text files (and not binary files)? Grep has an option to exclude binary files, so I thought find probably has a similar feature, but I've been unable to find it.

Programming :: Find And Replace A String In A File Using Perl Command From Bash Script?

Feb 14, 2011

I wanted to find and replace a string from a perl file. I have written a script in bash which runs the following command.

perl -pi -e "s/$findstring/$replacestring/" testfile
where as $findstring = print F_WC_TMP"$line
and $replaceString = $line = join ' ', split ' ', $line; print F_WC_TMP"$line

But when I am running the above command, i think it is replacing the $findstring with the above mentioned string and hence it contains a $line, it is looking for the variable $line and not finding the exact string. I am confused about how to search for a string that contains $ in it and replace it with another $string.

Ubuntu :: Correct Usage Of Perl Expression In 'rename'-shell Command

Jan 21, 2011

I want to rename some files in one directory and found the command 'rename' most appropriate.

Changing the file extension is easy since there are lot of examples for this.

But now I want to rename my files like this:

'somePrefix_blablabla.ext' --> '0_blablabla.ext'
'somePrefix_blablablablabla.ext' --> '0_blablablablabla.ext'

I DON'T want an incrementation, just the leading prefix '0_'

correct perl expression syntax for this?

Programming :: Using Grep And Regular Expression To Find Class References In C++ File?

May 28, 2010

I'm trying to math all class references in a C++ file using grep with regular expression. I'm trying to know if a specific include is usuless or not, so I have to know if there is a refence in cpp. I wrote this RE that searches for a reference from class ABCZ, but unfortunately it isn't working as I espected:

grep -E '^[^(/*)(//)].*[^a-zA-Z]ABCZ[]*[*(<:;,{& ]'
^[^(/*)(//)] don't math comments in the begging of the line ( // or /* )
.* followed by any character


Well, I can get patterns like this:

class Test: public ABCZ{
class Test: public ABCZ {
class Test : public ABCZ<T>

Ubuntu :: Find Command Does Not Find All Files?

Aug 9, 2011

The find command does not seem to find all files in my directory hierarchy. My home directory is automounted from a server. The command to illustrate this is:find | sed -e 's/^.///' | sed -e 's//.*//' | sort -uThe result misses several directories. Likewise, a find of a particular file, like:find . -iname *sample* -printwhere sample_file.txt resides in one of the directories that is missing in the first find command, finds nothing

Programming :: Perl Can't Find The

May 18, 2010

I am following a gtk2-perl tutorial, so I wrote the test program, installed gtk2-perl, and got this error:


Can't locate in @INC (@INC contains: /usr/lib/perl5/site_perl/5.10.1 /usr/share/perl5/site_perl/5.10.1 /usr/lib/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib/perl5/core_perl /usr/share/perl5/core_perl /usr/lib/perl5/current /usr/lib/perl5/site_perl/current .) at ./ line 7. BEGIN failed--compilation aborted at ./ line 7.

I googled, and figured out it's part of some Readonly module.But how do I install it? Preferably using the Arch package manager?

Ubuntu :: Bad Interpreter: Can't Find Perl In Synaptic Either

Oct 31, 2010

I downloaded a Perl script from off a page on the Internet, and tried to run it. It displayed its source in the web browser. First of all, I am in the cg-bin containing my cgi file and the file permissions are set to 755. I open the Terminal in this folder and run ls, which lists my file called hello.cgi; I run hello.cgi, and get a not found error, and run ./hello.cgi and get source code less comments:


me@fast:~/Files/Website/perl-dropdown/cgi-bin$ ls
hello.cgi redir.cgi
me@fast:~/Files/Website/perl-dropdown/cgi-bin$ hello.cgi


Next I open my Synaptic and search for perl, so I can reinstall it. I find nothing. I navigate to /usr/bin and eventually find perl and perl5.xx as well.

General :: Refine The Find Command?

Jul 12, 2010

Ive tried to rsync from one ~/home on hdd a, to ~/home hdd b, using a live cd, but it returns a load of; eg:

rsync: opendir "/media/a2ab9331-effd-4855-8e0a-6c7f1a9d63b5/home/nnjond/.Skype" failed: Permission denied (13)

So i think i should fresh install and it would be convenient if i knew the refined commands to locate the saved files in /home hdd a, since 02_06_10 (not including all the hidden or deleted files), and then copy to a memory stick using the nautilus gui.
